Re: [Paparazzi-devel] solved many problams with my lisa/m

[Piotr Esden-Tempski]

Hi,

If I understand you correctly you pulled up the CS pin permanently making 
communication to the barometer permanently impossible.

Am I right in the assumption you were not using master branch of paparazzi for 
your tests? To my knowledge only master branch has support for the MS5611 
connected to SPI.

If you use master you need to edit conf/firmware/rotorcraft.makefile replacing:
BARO = BARO_ASPIRIN
with
BARO = BARO_SPI

then the barometer should be read out correctly as well as all other IMU 
sensors with no hardware modifications necessary.

I hope this helps.

Cheers Esden
